Modern models of refrigeration equipment are often equipped with automatic moisture removal systems, but even in such units it is periodically necessary to completely disconnect from the network. Owners of equipment Stinol may be faced with a situation where an ice crust builds up on the walls of the freezer, or a general cleaning of the interior space is required. Despite the presence of the function No Frost in many modifications, engineers recommend completely defrosting the device at least once a year for prevention and hygiene.
The process of removing ice in two-chamber models has its own characteristics that distinguish it from defrosting single-chamber analogues. Here it is important to take into account the separate cooling circuits and the features of air circulation between the upper and lower compartments. Incorrect actions can lead to damage evaporator or failure of temperature sensors, so knowledge of the exact algorithm of actions is critical for the durability of the equipment.
In this article we will analyze in detail all the stages of preparation, the process of thawing the ice and the subsequent startup of the unit. You will learn why you should not use a hairdryer or hot water, how to quickly clean up the device, and what to do if, after turning it on, it does not get cold for a long time. Compliance with these rules will allow you to maintain warranty obligations and extend the service life of your Stinola.
Determining the type of defrosting system in your Stinola
The first step before starting any manipulations is to accurately determine the defrosting system installed in your model. Two-chamber refrigerators Stinol can be equipped with two main types of systems: classic drip (Drop Systemin the refrigerator compartment and No Frost in the freezer, or a complete system No Frost in both chambers. The frequency of the necessary procedures and the methodology for carrying them out directly depends on this.
If drops of water periodically appear in the refrigerator compartment on the back wall, which flow into the groove, and ice forms in the freezer, then you have a combined system. In this case, complete defrosting is required less often, but it is still necessary to clean the drainage channels. In models with full No Frost ice should not form at all, and the need for defrosting arises only for washing or if the automation malfunctions.
Understanding the design will help you avoid unnecessary actions. For example, in systems No Frost there is no need to wait for water to drain from the back wall of the refrigeration chamber, since it physically should not be there in operating mode. The main attention is paid to the freezer compartment and the evaporator hidden behind the plastic panel.
Preparing the refrigerator for defrosting
High-quality preparation takes up to 40% of the total procedure time and guarantees the safety of food and cleanliness in the kitchen. Before disconnecting the device from the power supply, you must empty the cameras of their contents. Products should be transferred to thermal bags, wrapped in blankets or temporarily placed on the balcony if the temperature is below freezing.
After removing the products, you need to remove all removable elements: shelves, drawers, egg trays and baskets. They should be washed separately with warm water and a mild detergent. Plastic parts should not be washed with hot water, as temperature changes can cause them to crack or become deformed.
- 🧊 Empty the chambers of all food and pack them to keep them cold.
- 💧 Cover the floor in front of the refrigerator with absorbent rags or towels to collect water.
- 🔌 Unplug the appliance and move it away from the wall to gain access to the back wall.
- 🚪 Leave the doors of both chambers completely open for air circulation.
It is important to prepare a container to collect water if you plan to speed up the process of melting ice in the freezer. Also check that the drainage hole in the refrigerator compartment is not clogged, since during defrosting the main flow of water will flow through it. If the hole is clogged, it must be carefully cleaned with a special brush or soft wire before melting begins.
☑️ Preparing for defrosting
Natural defrosting: algorithm of actions
The safest method recommended by the manufacturer is natural thawing. This method takes longer - from 10 to 24 hours depending on the thickness of the ice and the temperature in the room, but it eliminates the risk of damage to the plastic elements of the case. aluminum evaporator and plastic body elements.
After you leave the doors open, the slow melting process begins. In two-chamber models Stinol water from the freezer may flow to the bottom or evaporate if a container is provided to collect condensate behind the rear wall. However, if there is a lot of ice, water can flow over the edge of the freezer, so control is necessary.
⚠️ Attention: Never try to speed up the process by picking at the ice with a knife, screwdriver or other sharp objects. A puncture of the evaporator wall will lead to an immediate release of refrigerant and expensive repairs, which are often not economically feasible.
During the process of natural defrosting, it is important to ensure good ventilation in the room. Warm air speeds up the melting, so you can open the windows or turn the air conditioner on to heat (without directing the air flow directly to the refrigerator). Periodically check the rags on the floor and change them when they get wet to avoid damage to the floor covering.
Accelerating the process: acceptable methods and risks
If time is running out, owners often look for ways to speed up the melting of ice. There are methods that are acceptable with caution and those that are strictly prohibited. Safe, but requiring control, include the use of a fan directed into an open chamber, or containers with warm (not hot!) water installed on shelves inside the freezer.
The method with containers works on the principle of heat exchange: warm water gives off heat to the ice, accelerating its melting. It is important to change the water in containers as soon as it cools down. This method is effective for two-chamber models, where the volume of the freezer compartment allows you to place several containers.
Using a hairdryer is permissible only at a minimum temperature and from a long distance, constantly moving the air flow. However, manufacturers Stinol do not recommend this method, since local overheating of the plastic can lead to its deformation or cracks. In addition, the hair dryer creates a risk of moisture getting inside the electrical components.
- 🌡️ It is acceptable to use bowls of warm water (about 40-50 degrees) placed on a wooden board inside the chamber.
- 💨 You can direct the fan to the open freezer to circulate warm air.
- 🚫 It is forbidden to pour boiling water directly onto the ice or the walls of the chamber.
- 🚫 It is prohibited to use hair dryers or heaters in close proximity to the plastic.
⚠️ Attention: A sharp temperature change can cause cracking of the internal plastic lining. Microcracks will subsequently become places where bacteria and unpleasant odors accumulate, which will be difficult to remove.
Features of defrosting the No Frost system
Owners of models Stinol with the system No Frost often mistakenly believe that their refrigerators do not need to be defrosted at all. This is a misconception. Although the automation itself turns off the heating element to defrost the evaporator, once every 6-12 months a complete shutdown is required for hygienic treatment and checking the drainage system.
In such models, the main ice is hidden behind the back panel of the freezer. If you notice that the freezer has stopped freezing, and you hear noise from behind or see frost, the melt water drainage channel may be clogged. Complete defrosting within 24 hours will allow the ice inside the mechanism to melt and clean the channel naturally.
Why does ice still freeze in No Frost?
This happens due to a broken door seal, frequent opening of the chamber, or a malfunction of the defrost sensor. Moisture from the air penetrates inside and freezes on the evaporator.
When defrosting No Frost pay special attention to the fan. If it has been blocked by ice, once completely thawed and dried, it should begin to operate silently. Also check the rubber door seal, since it is its wear that most often leads to problems in forced air circulation systems.
Completion of the procedure and first start-up
After all the ice has melted, you must thoroughly wipe all surfaces dry with a soft absorbent cloth. There should not be a drop of water left, especially in the recesses and around the drainage hole. A humid environment promotes the rapid growth of mold and the appearance of a musty smell.
Assemble the refrigerator in the reverse order: install shelves, drawers and trays. Allow the plastic and metal to dry completely and warm up to room temperature. Only after this can you turn on the device to the network. It is better to perform the first start without products, allowing the unit to run idle for 2-3 hours until the operating temperature is reached.
| Stage | Action | Execution time |
|---|---|---|
| Preparation | Release of chambers, shutdown | 15-20 minutes |
| Defrosting | Natural melting of ice | 10-24 hours |
| Cleaning | Washing and drying internal surfaces | 30-40 minutes |
| Startup | Turning on and setting the temperature | 2-4 hours |
If after turning on the refrigerator does not work correctly, If it doesn't turn off for a long time or makes unusual sounds, there may be moisture in the system or a power surge. In such cases, it is recommended to let the equipment stand unplugged for several more hours to completely evaporate moisture from the electrical contacts.
Common mistakes and precautions
The most common mistake is haste. Trying to break the ice or knock it down with heavy objects leads to fatal damage. Repairing the evaporator in two-chamber refrigerators Stinol often requires sealing the system and charging with freon, which can cost up to 70% of the price of a new device.
Another mistake is turning on a wet refrigerator. Residual moisture in the drainage or on the shelves can cause a short circuit in the control system or lead to the formation of a new ice plug in the coldest place immediately after starting.
- 🛑 Do not use aggressive chemicals to remove ice or wash plastic.
- 🛑 Do not turn on the device if you smell or see burning sparking.
- 🛑 Do not place hot food in a refrigerator that has just been defrosted and running.
⚠️ Attention: Specifications and service requirements may vary slightly depending on the specific series and year of manufacture of your model. Always check the official user instructions supplied with the device.
Frequently asked questions (FAQ)
How long does it take on average to defrost a two-chamber Stinol?
The time depends on the thickness of the ice and the temperature in the room. On average, the process takes from 10 to 18 hours. If the ice layer is minimal, 5-6 hours may be enough. Speeding up with a hairdryer reduces the time, but increases the risks.
Is it necessary to remove the freezer completely?
Removing the metal box of the freezer is not required and is not recommended, as this can damage the fasteners or tubes. It is enough to remove the plastic drawers and shelves.
Why does the refrigerator not freeze for a long time after defrosting?
This is normal. The compressor takes time (from 2 to 5 hours) to cool the entire volume of air and walls to the specified temperatures. Do not load food at this time.
Is it possible to wash the inside of the refrigerator with water from a hose?
Absolutely not. Water should not get into electrical parts, lamps or ventilation openings. Use only a well-wrung out cloth.
What to do if an unpleasant odor appears after defrosting?
It is necessary to re-wash all surfaces with a solution of baking soda or citric acid. Check the drainage hole - often the source of the smell lies in stagnant water or mold inside the channel.
